Hi Awal. Interesting problem. Have you tried another pair of leads? What source are you using please, cd tuner etc? I noticed the the names for the five audio/video inputs can be customized by the user, Maybe there is a firmware issue? With the unit being surround sound Have you tried running in 2 chanels only?

I'm guessing you don't know for sure that it even needs fuses. They don't go out like they used to, as everything is controlled by a microprocessor(computer within your unit). I would suggest, that you, with the power plug pulled out, use an ohm meter to be sure that each fuse is shorted. If you need further assistance, or would like to inquire about a repair, please visit my website at audioserviceclinic.com. Thank you.

YOU ARE NOT RIGHT IT SHOULD GIVE AT LAEST A LOW VOLUME SOUND WITH A LOT OF DISTORSION AND A CRACKING NOISE IF DOES I GUESS THAT YOU HAD THIS AMP IN A PLACE WITH A LOT OF HUMIDITY AND YOU HAVEN'T WORK IT FOR SOME TIME IF I AM RIGHT PUT YOUR AMP IN THE SUN AND WORK IT FOR 10 MIN WITH A 5 MIN BREAK LET ME KNOW THE RESULTS

IF THE FUSE YOU ARE PLACING IS THE SAME TYPE AS THE ORIGINAL YOUR AMP HAS A PROBLEM WHAT YOU MUST DO IS TO SLIGHTY INCREASE FUSE BY 100 MAMPS PER TIME IF IT IS IN THE TRANSFORMER CIRCUIT YOU CAN INCRESE IT BY 2 AMP MAX IF IT IS IN THE MOSFETS CIRCUIT YOU CAN INCRESE IT BY A MAXIMUM OF 500MAMP LET ME KNOW THE RESULTS
